Application filed December 26, 1923. Serial No. 682,759.

To all whom t may concern.'

Be it known that I, JorrN F. Casier, a

citizen ot the United States, residing atV Portland, county ot Multnomah, State of Oregon, have invented certain new and usetul Improvements in Molds, of which the tollowing is a specification.

My invention relates to molds in general, and particularly to mold devices adapted `tor moulding concrete `building brick and the like, the object being to provide 'a device whereby concrete brick may be moulded in sand molds.

I accomplish the above object by means ot the construction illustrated in the accompanying drawing, which is a part ot this application tor Letters Patent, like characters ot reference indicating like parts throughout the several views thereof, and inwhich: i i

Figs. 1, 2, 3, 4 and? lare sectional perspective views ot my device as it appears in the various steps of its use; Fig. 6 is a perspective view ot the pattern board; and Fig. 7 is a perspective view upon an enlarged scale Ot one of the filling tunnels.

In general my device consists ot a pattern board having a plurality ot patterns mounted thereupon, a mold box adapted to embrace said patterns, a tollow plate adapted to lie between said pattern board and said boX and to receive each ot said patterns through a suitable respective oritice therein, and a tunnel board provided with a plurality ot tunnels, one such funnel to each ot said patterns.

The pattern board, which' is illustrated in detail in Fig. 6, is a flat board 8 provided with a plurality ot patterns 9, and ears 10 disposed upon opposite edges ot said board, and within which ears are secured dowel pins 11. Handles 12 are also provided for lifting said pattern board, which handles may conveniently be mounted upon said ears, as shown.

A tollow board, preferably ot iron plate, 13, is provided, with orices adapted to receive said patterns 9, the edges ot each ot said orifices being beveled towards the lines ot juncture ot said patterns With the pattern board 8, as shown in Figs. 1 and 2. Said follow board is provided with ears 14 adapted to register with the ears 10 upon the pattern board 8, and to receive the dowel pins 11 through orifices in said ears 14.i

A mold `box 15 is provided to embrace the patterns 9, said box having an open top and'bottoi'n, and being provided with ears 16 adapted to register withthe ears 14 and 10 previously described, and to receive the dowel pins 11 through suitable orifices in said ears.

A. tunnel plate 17 is also provided, havingV V14 and 16.

In use the pattern board 8 is deposited upon -themoulding floor or table with the patterns pointing upward, and the box 15 placed thereupon. Sand'` is thereupon rammedinto the boX lfand a board 20' placed on the top ot the box 15. Said cover 20 and the pattern board 8 are then clamped together by clamps well known to the foundry art, and therefore not illustrated in the drawing, and the whole turned over into the position shown in Fig. 2. The pattern board 8 is then removed together with the attached patterns 9, leaving the device as shown in Fig. 3, with the tollow board on the top. The tunnel board is then placed in position as shown in Fig. 4, and the liquid concrete poured into the molds through the tunnels.

Each of the tunnels is constructed to iit into its respective mold leaving a space therebetween ot substantially a constant width, and the body 21 ot the tunnels is substantially ot the same shape as that ot the mold. Each tunnel is secured to the tunnel board with the body below said board, and with an upward flaring top 22 projecting above the board, as shown in detail in Fig. 7. Adjacent the lower end ot each funnel slots 23 are provided through which the liquid concrete is deposited within the mold. The purpose ot such tunnels is to introduce the concrete into the mold in a manner that will not break down the surface ot the mold. Liquid concrete is poured into the tunnels until it stands slightly above the top ot the follow plate 14, whereupon the funnel plate with the tunnels attached thereto is slowly withdrawn, letting the liquid concrete settle into the molds. Atter the funnel board has been removed the tops of the contentsof the molds are slicked ofi'l smooth with "the top of the follow board, and then said follow board and the box l5 are removed, leaving` the sand mold with the moulded product therein upon the board 20, as shown in Fig. 6.

My device may be made of any size, and constructed of any materials deemedconvenient and suitable for a device of this character, and while I have illustrated and Adescribed `a form of construction found desirable-in materia'lizing my invention, I wish to include 1n this applicationall mechanical equivalents and substitutes that Vanda follow-board adapted to lie upon said pattern board, and having orifices therein to receivelsaid patterns, each of said orifices having beveled edges adapted to coincide `with the line of junctureof the respective patternwith said pattern board.

-2. 'In a moldza pattern board having a maan@ pluralityY of patterns secured thereupon; a follow board adapted to lie upon said pattern hoard, and having` orifices therein to receive said patterns, each of said orifices having beveled edges adapted to coincide with the line of uncture of the respective pattern with said pattern board; and a funnel board adapted to rlie upon said follow board, and haif'ing a plurality of funnels thereupon, each funnel being adapted to enter the mold left by the withdrawal of the pattern board and its attached patterns.

3. In a mold: a pluraliy of molds; a funnel board adaptedl to cover said molds; a plurality of funnels upon said funnel board, each of said funnels comprising a body of substantiallythe shape of the mold into which it is adapted to extend and provided with orifices at the lower end thereof, and an upwardly flaring top.

In witness whereof I claim the foregoing as my own I hereunto afliX my signature in the presence of two witnesses, at Portland, countyof Multnomah, State' of Oregon, this 9th day of Aug., 1923.
